Peter Minuit was born in the city of Tournai (presently part of Wallonia, Belgium) in the Southern Netherlands, to Wesel in Germany, in order to avoid Spanish Catholic colonials, who were not favorably disposed toward Protestants.
His surname means "midnight" in French. After his father, died in 1609 and Peter took over management of the household and his father's business. Peter had a good reputation in Wesel, attested by the fact that he was several times appointed a guardian. He also assisted the poor during the Spanish occupation of 1614–1619. Minuit married Gertrude Raedts on August 20, 1613. Gertrude was from a wealthy family and she probably helped Peter Minuit establish himself as a broker. A will drawn up in 1615 in the Dutch city of Utrecht, mentions "Peter Minnewit" as a diamond cutter. Whether he traded in other items is unknown. By 1624, the city was in an economic decline and in 1625, he had left Wesel and like others, went to Holland. At first, Gertrude went to stay with her relatives in Cleve.
Minuit joined the Dutch West India Company, probably in the mid-1620s, and was sent with his family to New Netherland in 1625 to search for tradable goods other than the animal pelts that then were the major product coming from New Netherland. He returned in the same year, and in 1626 was appointed the new director of New Netherland, taking over from Willem Verhulst. He sailed to North America and arrived in the colony on May 4, 1626.
